This is what I've come up with so far for converting SFB to unity.
Unity Hull: From the SFB SSD take the total number of boxes in the ship outline, add the excess damage boxes and divide by 10. There are only 2 ships that this doesn't work for and they are only off by 1 hull. (D7 comes out at 10 instead of 9. Large Freighter is 8 instead of 9.)
Unity Engines: Take the total power for the SSD, subtract the arming cost of all weapons, divide by the move cost, and then divide by 3.33. For ships with move cost of .33 add 2 to the final total. This works for about 70% of the ships.
Unity EPR: Looks like it maps straight to the SFB Move Cost.

Unity Screens: Fore and Aft match to shields 1 & 4, total shield boxes divided by 3.33. Starboard and Port add shields 2 & 3 or 5 & 6 and divide by 6.66. This works for about 70% of the shields.
Clearly there are some factors that I am missing in the Engines and Screen calculations. But most of the numbers are only off by 1. The exceptions are the Front screens on the Burke FF, low by 2 (5 instead of 7), & Texas CL low by 3 (5 instead of 8. I think this is because the armor was added to the front shield.). Also the Engines of the FD7 Swiftsword calculate high by 2 (8 instead of 6. I think the 6 should have been a 7 like the other Fast cruisers.).
